$PECIFICATION forming part of Letters Patent No. 397,137, dated February5, 1889.

Application filed November 1, 1888. Serial No. 289,771. (No model.)

view of the end of a car with a coupler em-' bodying the inventionattached. Fig. 2 shows detail perspective views of the operatingcamblock and the locking device. Fig. 3 is a central verticallongitudinal section through the draw-heads.

Referring to the drawings by letter, A designates the end of a carhaving the draw-bar B and draw-head 0 attached in the ordinary or othersuitable manner. The draw-head has its floor and sides outwardlydiverging or flaring, and the floor is provided with a centrallongitudinal recess, 0, in which the lower edge of the outer portion ofthe d awbar is secured. The said outer portion is formed into acoupling-hook, D, the upper edge of the point of which is about parallelwith and a sufficient distance above the tiaring portion of the floor ofthe draw-head and ends within the draw-head. Just in rear of saidflaring portion of the floor is the vertical shoulder (I, from whichruns outward in the point the longitudinal recess 1', for a purposehereinafter explained.

E is the upper coupling-hook,.withthe end of its shank reduced andpivoted in a recess in the shoulder formed'by the shank of the hook Dand the inner portion. of the drawbar. The hook E has its point facingthe hook D, and is provided with the vertical shoulder 6 immediatelyabove the shoulder d of the lower hook, and the triangular projection e,that enters and fits in the recess (1 when the upper hook is closed onthe lower hook.

F is a strong plate-spring secured to the rear portion of the draw-bar,and with its free end bearing down on the shank of the hook E to forcethe latter into engagement with the lower hook.

G is the link of ordinary construction, the end of which in entering thedrawhead will strike against the inclined edges of the two hooks, forcethe hook E upward, and fall behind the shoulder (Z of the lower hook,the spring then forcing the upper hook downward, as described.

It is evident that the link may be coupled at one end by a pin to adrawhead of ordinary constructitm.

II is a vertical shaft journaled in the roof and floor of the draw-headon one side of the couplinghooks in rear of the points thereof,

and provided with the horizontal projection 71., which, when the hooksare engaged, can be turned upon the shank of the upper hook and preventtheir disengagement, and consequently prevent the link from entering andthe cars from coupling. The said shaft has on its upper end, outside thedraw-head, a head or handle, 71., by means of which it may be turned.

I is a vertical shaft journalcd in the roof and floor ofthe draw-head inrearof the hookpoints and on the side thereof opposite to the shaft H,and i is a lever or hand-wheel on the upper end of the said shaft Ioutside the drawhead. The shaft I has secured to it within thedraw-head. a 1uadrant-shaped cam-block, J, secured at its angle to 'thesaid shaft and provided on its convex face with the inclined cam-ridgeK, similar to a screw-thread, and engaging under the shank of the upperhook, E, so that when the cam-block turned in the proper direction thesaid ridge will lift said hook out of engagement with the lower hook,thereby releasing the link.

I) is a cam-ridge similar to and below the ridge K, which, when thelatter ridge lifts the upper hook, lifts the adjacent end of the linkunder which it rests above the shoulder d, which might hold the link in'the draw-head when the upper hook is raised.

The head It and hand-wheel t' may be situated above the platform of thecar; but, if desired, the shafts II and I may be extended up throughbearings secured to the car end, so that the head and handle will beabove the ioo car, and the brakeman can operate them from the topthereof. This combination is shown in Fig. 1.

Having described my invention, I claim- 11. In a ea1'-cou lcr, thecombination,with a link of ordinary construction, of a pivotalcoupling-hook l'laving the face ot' its point downward and a suitableshoulder between its point and shank, and a eam-block secured to avertical shaft '()111:1ialet'liii the draw-head in rear of the point ofthchook and provided with inclined cam-ridges that engage under the hookand the link, substantially as described.

2. In a car-coupler, the colnbinatiml, with the draw-head having theouter portion of its floor inclined downward and outward and thedraw-bar having its outer portion secured in a central longitudinalrecess in the said floor, and formed into an upwardly-tacin couplinghookprovidml with a suitable shoulder between its point and shank, of adownwardlyfacing coupling-hook pivoted to the upper edge of thedra\\'-bar and provided with a suitable shoulderbetween it s point andshank, the spring secured to the draw-bar and. hearing down on the shankof the pivoted hook, and the quadrant shapedcam-block secured to avertical shaft and provided with inclined cam-ridges en gaging under thehook and the link, substantially as described.

In a car-coupler, the combination, with the link of ordinaryconstruction, the lower fixed iipwardly-l'acing cou iling-hook having avertical shoulder between its point and shank, the upper pivoteddowmvardly-tacing coupling-hook provided with a similar shouldcr betweenthe point and shank, and the quadrant-shapcd rot atory eam'blockprovided with two similar inclined cam-ridges,the11ppcr one of whichengages under the shank of the PlX'Ol'Od hook, and lifts the pointthereof out of the link, while the lower one simultaneously lifts theinner end of the link above the shoulder of the lower hook,substantially as specified.

at. The combination, with the draw-head having a flaring mouth, thedraw-bar having its outer portion :t'ormed into the hook I), seated in arecess .in the draw-head and pro vided with the shoulder d, and recess(1, the upper pivoted hook, E, provided with the shoulder e andprojection e, and the spring F, of the shaft I, journaled in the floorand roof of the draw-head, the hand-wheel i on the up per end of saidshank, and the quadrant shaped cam-block secured to said shaft andprovided with the inclined cam-ridge K to engage under the shank of thepivoted hook, and the similar cam-ridge, L, to engage under the enteredend of the link, substantially as specitied.

5. In a (aw-coupler, the combination of the lower 'upwardly- Ifaeingeoupl in g-l look secured to the tloor of the draw-hem], the upperdownwardlyd'acing eoupling-hook pivoted to the draw-bar, and the shaftll, journaled in the draw-head, having the handle it. on its upper end,and provided with the lateral projection 71, adapted to be turned uponthe shank of the upper hook and keep the ,latter, down on the lowerhook, substantially as specified.

In testimony thatI claim the foregoing as my own I have hereto al'tixedmy signature in presence of two witnesses.
